[Einstein Toolkit] #1645: simfactory should create exe directory

#1645: simfactory should create exe directory ------------------------+--------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: defect | Status: new Priority: minor | Milestone: Component: SimFactory | Version: development version Keywords: | ------------------------+--------------------------------------------------- Using virtual (--virtual) configuration one can wrap a Cactus config (or at least the parts that simfactory cares about) around an existing executable. Simfactory then copies the executable to exe/cactus_sim (or whatever), however it assumes that exe already exists. Since exe is not part of the Cactus checkout, simfactory needs to itself ensure that it exists. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1645> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1615: TOVSolver shares parameters from GRHydro -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: TOVSolver | -----------------------------------+---------------------------------------- Zach Etienne was looking at TOVSolver to use it for a test case in IllinoisGRMHD (and to compare to GRHydro). He found that it Turns out all but one of the parameters that are shared with GRHydro are unused in TOVSolver: These need to be removed: USES real rho_abs_min USES real rho_rel_min USES REAL initial_rho_abs_min USES REAL initial_rho_rel_min USES REAL initial_atmosphere_factor and that the one shared parameter that is actually used is GRHydro_rho_central. My suggestion would to remove these dependencies so that the initial data thorn can be used with other evolution thorns. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1615> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1059: simfactory silent error --------------------------------------+------------------------------------- Reporter: anonymous | Owner: eschnett Type: enhancement | Status: new Priority: optional | Milestone: Component: SimFactory | Version: Keywords: simfactory error message | --------------------------------------+------------------------------------- When sim submit -remote ... fails to queue a job because the allocation has been overdrawn, simfactory does not print any error message to screen (it is only hidden in the log file). Could it be made to print an error message to screen? -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1059> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#959: Move pthreads to ExternalLibraries -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- We should move pthreads support to ExternalLibraries (or to the flesh). I have asked CCT to create the respective repository. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/959> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1579: GRHydro does not build on Blue Gene/Q

#1579: GRHydro does not build on Blue Gene/Q ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Other | Version: development version Keywords: | ----------------------+----------------------------------------------------- Some of the C++ source files in GRHydro do not build on a Blue Gene/Q with IBM's compiler. The problem is that the compiler takes a very long time (>8h) even without (sic!) optimization. "The usual" playing with compiler options or changes to the source files had no effect. I consider this to be a bug in the compiler. A work-around may be to switch to Clang as C++ compiler. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1579> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#816: include SphericalHarmonicReconASCII from incoming in PITTNULLCode -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- Christian Reisswig provided a copy of SphericalHarmonicReconASCII and alternative thorn that reads in CCE boundary data (similar SphericalHarmonicRecon) but supporting a wider variety of input file formats (HDF5 among them, irrespective of the name). Used by SpEC and Llama. There are no docs or test cases as of now. Test data would be welcome (SpEC, Llama or Cactus provided, I don't think it makes a difference). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/816> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1637: MoL should automatically allocate storage for sufficient timelevels of evolved variables

#1637: MoL should automatically allocate storage for sufficient timelevels of evolved variables -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: MoL | -------------------------+-------------------------------------------------- The MoL thorn requires that all evolved variables have at least two timelevels of data, even if the integration method (e.g. RK4) does not need any past timelevels. It uses one of these timelevels as scratch space, potentially in addition to any other scratch space variables. In the case where at least two timelevels are needed for other reasons, this is more efficient than allocating an extra scratch space variable. Rather than requiring the evolution thorn to allocate at least two timelevels of storage for these variables, MoL should ensure sufficient timelevels via the flesh API. A related issue is that using timelevels for this purpose is wasteful in situations where the timelevel is not used for any other purpose, since the timelevel will be checkpointed even though it is only being used for temporary storage. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1637> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1754: _BSD_SOURCE in glibc apparently going away

#1754: _BSD_SOURCE in glibc apparently going away ------------------------+--------------------------------------------------- Reporter: rhaas | Owner: Type: task | Status: new Priority: unset | Milestone: Component: SimFactory | Version: development version Keywords: | ------------------------+--------------------------------------------------- I just stumbled accross https://lwn.net/Articles/634207/ which states: --8<-- Also in 2.20, the _BSD_SOURCE and _SVID_SOURCE feature test macros have been removed. The declarations formerly available under those macros are now under _DEFAULT_SOURCE, but, since it's the default, one need not set it explicitly. Roland's suggestion, though, was that most code would (continue to) want to use _GNU_SOURCE or one of the POSIX-specific macros. (See this article for an introduction to glibc feature test macros). --8<-- We use this in some of our option lists to make {{{M_PI}}} and {{{strdup}}} visible. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1754> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1252: Thorn configuration scripts should not be run if there are missing thorns -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- If there are thorns present in the thornlist which are not present in the source tree, Cactus currently displays the corresponding error message, and then runs the rest of the CST including thorn configuration scripts. Since these can build large external libraries (e.g. LORENE), it can be a long time before the user notices that the build has failed. I would prefer if Cactus aborted before running the CST scripts. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1252> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
